I know it's taboo, but I've been running a ZDZ 40 with the ignition and radio on the same 2200 mah Lithium battery and voltage regulator. Range checks and flys with no problem. RX is PPM.

Now I've got a new Brison 40 with C&H ignition that I want to swap out with the ZDZ 40 in a Patty Wagstaff Extra ARF. The Brison is 4 oz. lighter than the ZDZ, but I would like to stick with the single battery system.

My question is, has anybody experimented using a small capacitor bridging positive and neg. as is done on electric motors (for Electric planes) in order to suppress electrical noise? The capacitor would go where the voltage is still 6 volts, not on the engine side of the ignition module.

The Falkon ignition on the ZDZ seems very well shielded. The C&H seems less shielded. That's why I'm thinking the capacitor might help.

Thanks for any comments.
